Dual and multiple exposures to metal oxide nanomaterials: Unveiling histological and oxidative stress dynamics in Mytilus galloprovincialis.

Due to their increasing industrial applications, metal oxide nanoparticles (NPs) have emerged as significant environmental pollutants with potential ecotoxicological effects on aquatic organisms. This study evaluated the acute effects of binary and ternary mixtures of ZnFe₂O₄ (10 mg/L), SiO₂ (10 mg/L), and NiO (100 mg/L) NPs on Mytilus galloprovincialis. Following 96-hour exposures, oxidative stress biomarkers (SOD, CAT, GST, MDA) and histopathological alterations were assessed in gill and digestive gland tissues.

Assessing spinel zinc ferrite nanoparticles in aquatic ecosystems: Toxic threat or beneficial detoxifier for aquatic life?

The effectiveness of magnetic nanoparticles in removing pollutants during water treatment is well established, but their introduction into aquatic ecosystems raises significant toxicity concerns. This study investigates the histological and physiological effects of zinc ferrite magnetic nanoparticles (ZnFeOMNPs) on the Mediterranean mussel (Mytilus galloprovincialis) and examines the impact of concurrent exposure to these nanoparticles and the insecticide thiomethoxam (TMX). Mussels were exposed to nominal concentrations of ZnFeOMNPs (1, 10, 100 mg/L) both individually and with TMX.

Evaluation of Possible Toxic Effects of Boric Acid in Palourde Clam (Ruditapes decussatus) Through Histological Changes and Oxidative Responses.

The extensive utilization of boric acid, particularly in industrial and agricultural sectors, also engenders concerns regarding the toxicity of boron and its derivatives. Particularly, the behavior of boric acid at increasing concentrations in aquatic ecosystems remains poorly understood. In light of these concerns, this study aimed to investigate the toxicity of boric acid in bivalves, which occupy a critical position in the food chain.
